I think the only really good wireless applications are more PC related anyway. I don't know how many times I have heard...
"I'm setting up a projector with a PC and want to run video wireless."
With HD, sure it's nifty, but for what applications? Is this going to lead to wireless A/V receivers that have component inputs and wireless out that connect directly to TVs?
I would have to say - THAT would be cool. The idea of hanging a wi-vid 50" plasma over the fireplace and just having to figure out how to get a single power line cable to the display... Add surround with a single wi-vid center channel... Heck, power is already there.
It's a nifty idea, but wireless often has as many issues as just running the lines to begin with. And vaporware at trade shows has a nifty way of taking 5 -> 1,000 years before ever becoming an actual consumer product that is useful.
Let's keep our fingers crossed for something useful.
